No problems on windows on chrome-os either. Mikael S and I checked it on his linux box and one can indeed see anti aliasing when taking a screen dump (depends on resolution). So it's a linux rendering issue when taking dumps. That said: we can't do anything about it. Using rules (traditional approach) is pretty bad in screen dumps and even regular rendering, depending on zoom; there one has interaction between the font rendering and other graphic elements (rules). Btw, vertical extensibles are not different (take the bracket which has similar constructs). Interesting is that it is straight blob connections that can show these occasional gray pixels and it only seems to happen with a little overlap. Kind of a bug we think. Hans ps. One reason when I always use (x)ubuntu when i have to use a linux desktop is that it always was set up right wrt rendering fonts and anti aliasing. I might need to check that. - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

As far as I tried, neither tex.measured nor context.measured worked
(but I wouldn’t swear on it, maybe I had a different error).
I understand now that a dimension in Lua is just a string.
no, it is a number (scaled points or sp) but it can have a string
representation
I also messed a few thing up when I converted my macros from
measure-macros to measures.
Now my image calculations work again. Phew!

I need it as a dimension, since I do calculations with other dimensions

How should I do this correctly?
There doesn't appear to be any official interfaces to get the value of a

\definemeasure[mymeasure][10pt]
\newdimen\mydimen \mydimen=10pt
\definemeasure[measureexpr][1in + 27.73pt]
\startluacode

return tokens.getters.macro(namespace .. variable)
end
-- Gets the value of a measure and converts it to an integer in sp

local function get_measure(name)

-- Gets the \dimexpr-evaluated value of a measure, in sp units.
local function get_measure_expr(name)

-- Undocumented, but seems to work as expected.
return tex.getdimensionvalue(namespace .. name)

-- Print the values of the lengths.
print(("="):rep(80))
print("mymeasure:" , get_measure("mymeasure") )
print("mydimen:", tex.dimen["mydimen"] )
print("measureexpr:", get_measure_expr("measureexpr"))
print(("="):rep(80))
\stopluacode
\startTEXpage
\measure{mymeasure}
\the\mydimen
\measure{measureexpr}
\stopTEXpage
Thanks,

Indeed we can have:
local namespace = tokens.getters.macro("??measure")
function tex.getmeasure(name,asdimen)
local value = tex.getdimensionvalue(namespace..name)
if asdimen then
return value .. "sp"
else
return value
end
and when you want to avoid the namespace you can do:
function tex.getmeasure(name,asdimen)
local value =
token.getexpansion("\\tointeger\\measured{"..name.."}")
if asdimen then
return value .. "sp"
else
return tonumber(value)
end
end
which is some 4 times slower. It'sindeed not documented (although there
are some examples in accessors-001.tex) but it's in one of my todo's
because I can use it in some places (there ar emopre such todo's) after
which it will be discussed in one of the lowlelvel manuals
i'll add tex.getmeasure to the core (but a bit different)

First of all, lpaths are XPath implemented with Lua in ConTeXt. XPath seems to have as it primary purpose to address the nodes of XML trees. About your sources, the real issue here is to define whether you want TEI or TeX to be the format containing them. I mean, if you add explaining footnotes to your TeX file(s), XML won’t be source anymore. If you don’t want this to happen, you have to encode them in the TEI XML sources. One last suggestion about proofreading. This is something I learnt from personal experience. The first reading is much better to catch errors in the text than the subsequent ones. Having the text properly formatted and printed on paper helps a lot to spot errors. Reading source code is cheaper (no doubt), but the results will be poorer too.

Your guidance are most welcome :-)
you have to fight several issues:
- parshapes being reset at the end paragraph (handled here by luametatex

- parshapes operate on lines, not dimension (i might add an aletnative
one day)
- you use a bit old mechanism (checkout the luametafun-paragraphs chapter)
Now, is there a solution? It really depends on the circumstances, so
here is one.

fill SavedShape withcolor red;
setbounds currentpicture to OverlayBox;
\stopuseMPgraphic
\showframe

\startshapedparagraph[mp=shape:1]%
\setupalign[verytolerant,stretch]%
\hpos{test}{!}\samplefile{tufte}
\samplefile{tufte}

The "test" position is hard coded but should be namespaced, the ! can be
a \strut instead.
So, more thinking from the end of the text flow.

[NTG-context] update
Hi,
This weekends update:
- we're currently checking the upcoming math manual and in the process
we streamline some mechanisms
- as part of the BT presentation about par passes we introduced
\toddlerpenalty but we leave it to the user to guess what that is (it
fits into widow, club and orphan penalty collection)
- we could already produce pdf 2.0 but especially when one mises with
older files, some care is needed; the inclusion 'compact' mechanism has
been cleaned up a bit and the merge interface is converging (it has to
do with efficient font sharing, cleanup and fixing of files outside our
control); when one has issues with inclusion, try with compact= (set to
nothing)
- although we're mostly done with tagging it will get some attention as
we go; it's mostly about playing safe and getting valid pdf's
- for rhaban (posters) another fancy feature was added:
\startTEXpage[offset=1ts]
\samplefile{tufte}\removeunwantedspaces\space
\startshadow[contrastcolor=red,weight=100]\blue\samplefile{tufte}\removeunwantedspaces\stopshadow\space
\samplefile{tufte}\removeunwantedspaces\space
\startshadow[contrastcolor=red,weight=100,dx=0,dy=0]\blue\samplefile{tufte}\removeunwantedspaces\stopshadow\space

Hi, Hans! Thank you for the update! I'm curious about the following
issue: when I use Latin Modern (by default), a thick, filled line is
drawn next to the radical. However, when I use another font such as TeX
Gyre Schola, I get something similar to outlines-003.pdf, which is, in
turn, similar to the result of applying PDF effects. So, shouldn't this
result be the default? Thanks a lot again.
it depends on how a radical is composed; we try create an extensible
using snippets which looks better in the case of fontd where rules (have
to) have roun dcorners etc

I can't see any effect of weight parameter.
Using adobevariablefontprototypebold and adobevariablefontprototypelight is
working.
\starttext
\definefontfeature[whatever][axis={weight:150}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar
\definefontfeature[whatever][axis={weight:350}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar
\definefontfeature[whatever][axis={weight:550}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar
\definefontfeature[whatever][axis={weight:750}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar
\stoptext
Can it be something from with my font file ?
\starttext
\definefontfeature[whatever01][default][axis={weight=0250}]
\definefontfeature[whatever02][default][axis={weight=0500}]

The provided "*arabic" featureset should suffice for this font. Also
TEXpage is useful for this kind of MWE:
\definefont [Ahang] [file:Ahang-Regular.otf*arabic at 18pt]
\setupalign[r2l]
\startTEXpage[offset=1em]
{\Ahang تَشْكِيل كَسْرَة}
\stopTEXpage
In prehistoric ConTeXt version
2023.09.26 18:19
the diacritics look fine in both ConTeXt and unicode editor MS Notepad.
So if there is something wrong, it must be in a more recent version.
For comparison: Before applying Hans' patch, could you kindly send your
pdf of the MWE that shows the error? Mine is attached.
Ahang-Regular has no width settings for the marks so we need to zero
them. Tahrir_Regular has widths but these we explictly need to zero with
a pseudo feature then. (What are the assumptions when we do arabic? That
marks are to have zero width?)

Since I've become an expert on tuc files since yesterday (ha!): if I compare the tuc from
a mkiv and a mkxl run, I see that mkiv produces an entry ["lastrealpage"]=9 in
the references table, mkxl doesn't. This appears to be the relevant bit, and it is
connected with the replacement of realpageno by c_realpageno in line 638 of strc-reg.lmt
references.lastrealpage = texgetcount(c_realpageno)
Let's seen if we can make Thomas more of an expert as he's zooming in on
the issue:
extendregister {
metadata = { name = name },
references = { abel = label },
}
Let me know if you't see it.
Possibly related: I noticed last week that mkxl does not update the legacy
counter \pageno any more for every page.
i'll check it

[NTG-context] Re: Why don't footnotes appear in floats or figures?
On 4/22/2024 2:45 AM, Joel via ntg-context wrote:
I'm three days out from sending my work to an editor, and found some
serious problem: many footnotes just aren't rendering.
I have a history text that uses ConTeXt-SBL for the citations, as such,
it has lots of footnotes. Sometimes the footnotes are just in the main
text, but sometimes also in figure captions, inside floats, inside
tables that are inside floats, inside tabulations inside floats, etc.
What I find alarming is it is frequently not rendering all of the
footnote messages at the bottom of the page. The actual footnote number
within the body is rendered, but no number is listed in at the bottom of
the page. So I might see a list of footnotes, for instance, on page 1, I
only get footnotes 1, 2, 3, 5, and 6, but 4 was mysteriously skipped.

1 message
2 message
3 message
5 message
6 message
After a lot of trial-and-error and checking logs and checking my BibTeX
files for errors, running everything through BibTex Tidy, etc., and
failures to make a minimum working example, I found a single pattern:
If the footnote marker appears on the SAME page as the footnote text, it
has no problem rendering the footnote. But, if ConTeXt decides to move a
float a page or two later on--as it frequently seems to do---such that
the footnote marker and footnote text at bottom of page should be on
DIFFERENT pages, the footnote message at the bottom of the page won't
render.
I've seen some 2+ year old mailing list posts suggesting ConTeXt might
have issues with footnotes; they appear to be similar to my issue--is
that still a problem? Is there a fix or workaround? Old fixes I could
finding in the mailing list don't seem to work with current versions of
ConTeXt anymore.
you need to consider the complications of such notes ...
- tex needs to take the notes into account when determining a page break
- it does so by the insert mechanism
- when floats can't be placed they also become inserts (top and bottom)
- when there are inserts in inserts th eproblem becomes more complex (so
notes inside floats)
- in traditional tex deeply burried inserts disappearm less so in lmtx
There are things that are hard to get right. This works:
\startpostponing
\startplacefigure[location=here,title={test \footnote{oeps 1}}]
\blackrule[width=1tw]
here
\footnote{hello 1} and
\footnote{hello 2} and
\footnote{hello 3} done
\stopplacefigure
\stoppostponing
\dorecurse{10}{\samplefile{tufte}\par}
Because here the inserts (notes) will migrate but even then one can get
them out of order (unless we renumber, which then is sensitiev for
oscillation).
I occasionally wonder if top floats could be done more directly but
bottom notes still would have an out-of-sync problem

Those are just some examples; I intended for something to be printed

Since a document of this size will have a lot of messages, is there a
way to adjust the settings, from "show everything" to "show some" to
"show only serious errors"? Or maybe to use > to send the errors to
another file for careful study? (using Linux if that matters)
You can enable trackers like
\enabletrackers[figures.*]
But that just gives more log messages for debugging.
You get the list of all trackers with:
context --global m-trackers.mkiv
For your use case, directives are more helpful, like
\enabledirectives[logs.errors=*] (i.e. break at every error)
AFAIK that just handles missing characters, references and modules ATM,
but this information might be outdated.
You get all directives with
context --global m-directives.mkiv
often the log files has some summaries at the end

No, I must admit I don’t like the first two paragraphs. The question is “what
is ConTeXt,” and the answer is “we’re not LaTeX.” And why “infamous”?
I agree. It sounds the same as "we're not msword" or "we're not google
docs". (In the end the only thing that latex and context have in common
is that they use the tex language / ecosystem.)

I noticed that the PDF specification was published in 1993 yet ConTeXt was invented in 1991. The book suggests that PDF output was handled by the PdfTeX engine in MKII in 2005. What sort of output did the software produce before PdfTeX was introduced? Was this the same as the output produced by the software before the publication of the PDF specification? 2005 is when we started with luatex which is a follow up on pdftex, and pdftex is more a mid 90's thing; we immediately adopted pdftex (which made some believe that context depended on pdftex which is not true) anyway, we started with dvi which needs a postprocessor to go to some printer format like specific hp or more general postscript but also can drive viewers we went from epson dot matrix printer -> early 300 dpi laser -> 600 dpi laser printer -> high speed oce 512 dpi printer (metric) -> high speed oce 600 dpi printer (+ crappy canon color laser printer) -> fast page-wide hp color inkjet office printer in mkii all is controlled by backend drivers, that use so called specials to support color, hyperlinks, images so a workflow can have - dvipsone : high quality postscript - dviwindo : viewer with typeone support and hyperlinks - acrobat : postscript to pdf and as all these external backends have their demands we could handle all these things in an abstract way (that way one could also drive printer properties like duplex or paper bins etc from a tex job) that meant that when pdf came around we could almost immediately support most of the interactive features in a dvi -> ps -> acrobat workflow when pdftex came around the intermediate step of postscript could be avoided which btw was also possible with dvipdfm(x) so we also supported that so to summarize, it went from tex -> dvi -> printer format tex -> dvi -> postscript -> more generic printer format tex -> dvi -> pdf -> print from acrobat tex -> pdf -> print from pdf viewer in the meantime we are pdf (as from that one can produce other formats) Hans (btw, the fact that we could easily support pdf was also a reason why at that time some adobe folk in nl used documents produced by context to show somewhat extrems usage of interactive features, thanks to the fact that tex can adapt to such new situations, also via the dvi route in this case with pdfmarks; at that time pdf usage - and features - was a bit more dualistic: ps replacement format versus storage and preview format, but that's a different story; but it still shows in how the standard evolved) ----- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

Found it - and I'm embarrassed to say it was in my own environment file,
not in the lmtx distribution. I have a Lua function that prints
information about the computer model and the operating system into a
layer. Unfortunately, there was an "elseif" in there somewhere which
should catch exceptions (such as a raspberry pi), but instead of
concatenating the relevant return values to display in the layer, I had
a ' context (" on ")' in there (probably for debugging) which I forgot
about.
Sorry for the noise - I was getting too sophisticated for my own good...
No problem, is it a rpi 5? If so, how does that one perform?

Of course.
But you asked for wanted accessibility features:

We have \pdfbackendactualtext{visible}{alternative}, can we get
alternative text (ActualText) for images?
Not automatically, of course (if someone wants AI descriptions they can
implement a module), just as a keyword in \externalfigure?
we can add a description option that then can eb used in the wrapper
(not that it helps much to make an image accessible)
btw, someone showed me what this acrobat liquid mode does to a document
... the fact that one has to apply 'ai' to a document is a bad omen and
makes one wonder ... but anyway, big tech, big money, etc so ... (after
visiting a typesetting museum today one again realizes that a few
decades from now one will look back in a certain way, not all is progress)
one thing we need to keep in mind is that as soon as 'obsolete' and 'not
to be used' enters descriptions (which kind of contradicts the
flexibility of sofware) one can also wonder how older documents can ever
match a standard; i often get the impression that instead of some
thinking ahead we end up adapting to what can't be done or what went
wrong (and calling something a standard can then be a way to obscure)
anyway, one way or the other we will cope (and it depends on user demand
which in turn depends on organizational demand)

hyphens.
I tried it on overleaf and of ContextOnWeb with the same

when I overwrite an existing file subtituting a hyphen for three

It is not the pdf viewer since I get good or bad results in all, the
overleaf pdf preview tool, the context on web preview tool and the
mozilla integrated pdf viewer.
Am I missing something on the use of this ligature? (the question is
just out of curiosity, since I plan to create a command that adds a
hairspace after or before the dash, since I don't like it to stick to
some letters like "o".
Generally, “we” try to reduce active characters as much as possible,
that’s why -- and --- usually /don’t/ produce en or em dashes. You can
activate these ligatures as a font feature though (AFAIR
"latexhyphens", can’t find it…).
The name of the option has changes a few times and the current setting
is textcontrol=collapsehyphens.
Some editors and some fonts do automatical replacements.
In this case it could be the wrong symbol in the document, there are
many dashes in unicode which look similar in the input and output files.

linecorrection is older, textdisplay newer and both are mainly meant to
position boxed content (like images) in a way so that spacing looks
acceptable ... they are vboxes with spacing around them so not meant for
e.g. section heads or whatever text; it's for images, framed stuff,

Thanks for the new module math-goodriddance !
Indeed there are many mathematicians who are going to use the
\goodriddancemath command, and no doubt they are going to thank you,
even if they are very shy to come out.
Moreover this command can be used by people who want to transform the
output PDF into an audio file, because for instance the following
\usemodule[math-goodriddance]
\goodriddancemath
\starttext
\startformula
\int_{0}^{\pi} \sin(x)\dd x = 2.
\stopformula
\stoptext
gives
integral from 0 to 휋 , of sin of 푥 d 푥 equals 2
you cna be more ambituous:
\im { C \of (\openinterval{a,b}) \neq C^^2 \of (\interval{a,b}) \neq
C^^2 \of \interval{0,1} \neq C\of(\Omega) \neq 풞 \of (\Omega)}
or
\dm {u\of(b)-u\of(a)=\lim_{n\to+\infty} \parenthesis{f(x__1)\Delta
x__1+f(x__2)\Delta x__2+\ldots+f(x__n)\Delta x__n}}
so we can really get rid of a lot of math
as one can see in the attached output which is very useful for the blind
using an audio software.
yes, although unfortunately unicode never bothered to add some handy
stuff for that (while if did for other comparable things) but we'can get
around that
I now assume that you are willing to come up with the french
translations (that then can be validated by Alan). Do we actually have
serious german context math users, as I wouldn't trust Hraban and Thomas
on doing this?

Hi,
There is a new lmtx upload.
-- The svg inclusion via metapost has been upgraded and cleanup a bit,
using some more recent metapost features. There are some new (not yet
all documented metapost) features.
-- In the process, support for LCH colors has been added, which is
documented in the (eg luametafun manual).
-- The math manual is not yet there because we were distracted by
improving support for envelopes (penbased outlines) in metafun. This is
still work in progress, some is present and discussed in the manual, and
we'll come back to that sometime next month. Given the next item, we
also might need to change some in the manual (different focus).
-- Because we have users who have to conform to the European
Accessibility Act we have been wondering how to deal with that and at
Mikaels place there are two demands: distinctive colors and tagging and
especially math (somehow validators love to check that). Colors never
were an issue as they can be controlled, and tagging math neither,
especially because nothing was/is done with it anyway, but ... we are
happy that we found a reasonable (more modern and future proof) way out.
As explained / shown in the attached document we're basically forced to
choose a different approach with math (a pity as we worked hard to get
the rendering right but the attached file works fine in the viewers that
we tested).
-- We like to hear from users what other demands wrt accessibility there
are. We're not interested in the (commercial) big money aspects (of pdf
and tagging) nor in the politics behind it (changes over time). What are
the demands, so that we can see how to make it work or just work around
it (as it's kind of boring to cook uyp complex features , esp compared
to playing with metapost).
-- Furthermore .. the usual bits and pieces as discussed on the list and
otherwise.
-- If you have troubles (crash) you need to wipe the cache due to a
change in lua bytecode storage (no easy way to catch it).

We're done with math. After years of active development, Mikael and Hans have
decided to quit working on math, and concentrate on \METAPOST\ and handing over
to the next generation instead. We lost our user to the way more popular
alternative (frozen in stone standards). Also, we had it with suboptimal math
fonts, Unicode math not getting improved, MathML constantly being changed,
browsers dealing with math differently every few years, math archives getting
polluted with tons of useless tagged math.
There are other motivations, like the European union imposing strict rules with
respect to accessibility in educational content management systems, and Dutch
schools trying to get rid of math in favor of simple calculus, if at all. This
is
why the next iteration of the engine will no longer have a math engine:
MathLessTeX. Of course, in the beginning \MLTX\ will be compatible with \LMTX,
because we owe that to the users and we need to prototype the new engine anyway.
In order to get an idea of how we will get rid of the disturbing formulas, you
can load the module:
\starttyping
\usemodule[math-goodriddance]
\stoptyping
Until becoming the default setting, the command \typ {\goodriddancemath} will
bring you into \MLTX\ mode while \typ {\badriddancemath} will bring you back to
the obsolete \LMTX\ mode. Like:
\startbuffer
\usemodule[math-goodriddance] \goodriddancemath
Who wants to solve the equation \m {x + 1 = 4} or deal with the function \m {x
\mapsto
\root [3] {x}}, when we have AI around the corner to help us out with simple
and silly
things like the Pythagorean theorem: \m {a^2 + b^2 = c^2}, or even with more
advanced
math like geometric series: \m {\sum_{k = 0}^{+\infty} x^k = 1/(1 - x)}?
We will not support complicated nonsense stuff like:
\startplaceformula
\startformula
F__{1}{2}(a,b;b;z) = (1 - z)^{-a}
\stopformula
\stopplaceformula
When developing this Hans' Swedish improved a lot. {\language[sv] Den lilla del

befolkningen som handlar på IKEA och tittar på fåniga krimserier förstår kanske

\im {\sqrt {x + 1} = \sin(4 + y)}!}

Which gives us the beautifully typeset:

The image can't be more than \textwidth wide, and can't ever be more than

The problem I am getting with this code, and it does seem to be limiting the
images to be not bigger than those two dimensions above, is some of the images,
for reasons I can't understand, are appearing really tiny and aren't scaling up
to fill as much space as is possible. I can't explain why this is
happening--the images themselves are very very high resolution.
Is there any way to modify the code to make sure the image stretches up to be
the biggest it can, without exceeding the sizes I've listed?
Hi Joel,
AFAIK, if you don’t set at least either height or width, ConTeXt uses the
image’s resolution setting to calculate its size, and that is often useless.
(Maybe there’s also something wrong with ConTeXt’s max width/height, I don’t
know; I’m still planning to carefully check all options of image processing…)
You could try if "factor=fit" or "factor=max" yields the results you want.
As Hraban says, you only need to set one of height or width and Context works
out the other.
For your case I think you just need width=\textwidth, so
\externalfigure[#1][frame=on,width=\textwidth,maxheight=1.2\textwidth]%
where maxheight imposes the height size limit you mention.
If you still have problems with tiny images then I suspect that is a different
issue - something to do with the image file and the metadata about the image
size maybe? If you can share an affected image then perhaps start another
question with an MWE and upload the image somewhere.

You are correct. when i convert this svg to pdf via inkscape it works
like a charm.
But what is standard way of including an svg file with context if we
want to inkscape render the images?
\externalfigure[smile]
without any other settings, but inkscape must be callable on the command
line (which doesn’t work for me on MacOS any more, must investigate…).
\startMPcode
draw lmt_svg [ filename = "smile.svg"]
\stopMPcode
Now gives the attached but it took me a while to figure out what works.
An inkscape export adds for instance something (globally applied) that
is not in the svg file (which actually derived from tiger.svg as
mentioned in the file).
To be honest this is a horrible file and a good example of making things
more complex than needed (probably common in wysiwyg applications),
although we already had the machinery in the mp/pdf converter.
The biggest issue here is that one has to put some constrants in place
order to make it work in e.g. sumatra (mypdf) and acrobat (which here
actually does weird erratic things when I play with another test).
As with much complex svg, browsers also differ in interpretation o fsome
features so it's hard to figure out what to do when there are
conflicting demands. (Pointing to something that works tomorrow doesn't
mean it worked when we tried to implement something yesterday.)
For Hraben - who mentioned it - i also added support for group opacity
and transformed shades.
In the process I tried a few inkscape options (pdf export) but some
produce faulty files (with missing stuff) so i guess we have a complex
situation in general. That said, as long as one sticks to reliable and
clean code (plain svg) it should mostly work out.
Text is another matter because svg dropped glyph support so now
everything has to go through font features which in turn means that if
one uses svg as output format one has to specify every character with
possible abuse of a substitution feature that accesses it. So that is no
longer a real interesting option, unless of course one exports all text
as curves, just to be sure.
(I will extend general text suport but it will always be suboptimal but
then, svg is not a long term archival format anyway.)
No upload yet as i also want to do some cleanup,
ps. For metapost lovers, here is some of the trickery used:
\startMPpage[offset=1ts]
draw image (
fill (unitsquare xscaled 10cm yscaled 4cm)
withcolor svgcolor(0.5,0,0)
;
registerluminositygroup ("test") (
fill (unitsquare scaled 2cm) shifted (1cm,1cm)
withshademethod "circular"
withshadecolors (.6,.1)
) ;
applyluminositygroup ("test") (
fill (unitsquare scaled 2cm) shifted (1cm,1cm)
withshademethod "circular"
) ;
draw luminositygroup (
fill (unitsquare scaled 2cm) shifted (4cm,1cm)
withshademethod "circular"
withshadecolors (.6,.1)
) (
fill (unitsquare scaled 2cm) shifted (4cm,1cm)
withshademethod "circular"
) ;
draw luminosityshade (
(unitsquare scaled 2cm) shifted (7cm,1cm)
) (
withshademethod "circular"
withshadecolors (.6,.1)
) (
withshademethod "circular"
) ;
) ;
\stopMPpage
Not that intuitive and a bit ugly deep down but it works (there was no
need to extend mp btw as we already have graphic grouping in the engine).

We provide
\pgf@context@registercolor
\pgf@context@registergray
\pgf@context@registerrgb
\pgf@context@registercmyk
in colo-ini that hook into the context color mechanism so be careful
with patches. I'm not going to spend time on other solutions that can

[NTG-context] update
Hi,
Todays update has a fix for the compact mode slant interference (as
explained by Wolfgang a few days ago). Hopefully that works out well.
We (MS and HH) also managed to make curve detection more accurate (the
decision routine that is responsible for straight lines in the MP
output) so that extreme paths with control points way beyond reasonable
still produce the right output (before we could get a wrong bbox due to
clipping the curve in the backend). One can actually also force "always
curve" with "withcurvature 1" (more variants might follow) but that is
more or us to have a test option. Curvature detection is mostly a pdf
efficiency feature and normally users should rely on the default to work
okay.
Other new mp features are relative and absolute points which makes it
possible to define paths in a turtle graphics way (a bit like hlineto
and vline in postscript), a native "--" operator (equivalent but
somewehat more efficient on huge generated paths). The luametafun manual
has a chapter on paths that describes some of this.
Yet another new feature is "firstcontrol" and "secondcontrol" that is an
addendum to controls that makes both control points the same when only
one is given.
Finally there is a fix in mp where some directions, think { dir 120 },
gave the wrong result due to sign swapping (so it was seen as { dir 200}
or { dir -60 }) as side effect of negative zeros fed into tan2. This
became obvious when MS reprocessed a graphic, as last year we switched
from scsled (no bug) to double (long time bug exposed). (The bug is also
present in LuaTeX double/binary mode but it will be fixed there too.)
The rest is not (yet) worth mentioning,
Hans

The results happen when you use compact mode and is a result of
\glyphslant which keeps the value of the italic style even when you
switch back to the upright style.
Many thanks for your explaination,
using the low level commands
\glyphscale
\glyphxscale
\glyphyscale
\glyphslant
\glyphweight
directly can have side efects when at an outer level these are also
set, so you need to accumulate, like
\starttext

test} test
test {\glyphslant 500 test \glyphslant \numericscaled2.0\glyphslant
test} test
test {\glyphweight 100 test \glyphweight\numericscaled2.0\glyphweight
test} test
\stoptext
The problem is that compact mode uses them to apply the slanted feature
without any manual use of the commands from a user.
\enableexperiments[fonts.compact]
\definefontfamily[mainface][rm][TeX Gyre Termes]
[it={style:regular, features:{default,slanted}},
sl={style:regular, features:{default,slanted}}]
\setupbodyfont[mainface]
\starttext
\startstyle[style=italic]normal {\em emphasized} normal\stopstyle
\stoptext
The only way to mask the effect is to create a new fontfeature with the
minimum slant value and apply it to the upright style.
\definefontfeature [unslanted] [slant=0.001]
\definefontfamily[mainface][rm][TeX Gyre Termes]
[features={default,unslanted},
it={style:regular, features:{default,slanted}},
sl={style:regular, features:{default,slanted}}]
ok, i'll fix that (build is down so no update)

have « } » missing in your file, that is the closing brace after your
italic command
« {\it » at the end of your document.
Moreover you did not have a \stoptext in your file, and a math command
« \m » was not written correctly. Talking of math, I personnaly prefer
to enclose in-line math between dollar signs $, that is writing «
$\exists x \in H$ » instead of « \m{\exists x \in H} ».
Well, better stay with the modern ConTeXt approach of \m{}.
for regular inline math we just use \im{...} (which has an \dm{...}
companion with displaystyle

normally harmless so i can add an extra check but bookmarks can be a

With current latest (2024.02.27 09:21), LuaTeX gets boldened and slanted
for regular (but the other fonts cannot inherit the wider feature and
wider will not mix with boldened-30 [even when specified]).
For some reason, LMTX from current latest cannot get slanted and
boldened-30 (but it mixes the inherited wider feature in all fonts).
This began to behave differently in latest from 2024.01.08 11:23 (which
is my next version after the one from 2023.09.26 18:19).
Could anyone confirm the issue?
accumulating these effects is dependent on how the features that you use
are defined
in luametatex we have a bit more advanced mechanism (also relates to
compact mode) because th eengine is a bit more clever
just make sure that you don't add up features where one calcels the
other, so use for instance:
\definefontfeature[wide] [extend=2]
\definefontfeature[wideslant][extend=2,slant=.2]
\definefontfeature[widebold] [extend=2,weight=.1]
\definefontfeature[wideboldslant][extend=2,weight=.1,slant=.2]
\definefontfamily[mainface][rm][TeX Gyre Pagella]
[tf={style:regular,features:{default,quality,wide}},
it={style:regular,features:{default,quality,wideslant}},
bf={style:regular,features:{default,quality,widebold}},

You're missing the fact that the font has an issue. I can add a

#1\par#2\par#3\par#4ñ{\framed[frame=off,width=0.8\textwidth,corner=round,offset=1em,align=flushleft]%
{{\bf Beispiel}: #1\\
\qquad a) #2\\
\qquad b) {\bf #3}\\
\qquad c) #4
}
I get: tex error on line 493 in file ./prueba.tex: The file ended when
scanning an argument.
the macro seems to read to the end of file not detecting \par; I know
its the \par that causes the problem; I used ^^M also which I read is a
sinonym for return but it also does not work.
Help would be appreciated (my computer keyboard would appreciate it too...)
better start thinking something:
\starttext
\def\foo#1{<<<#1>>>>\par}
\startluacode
local s = [[
line 1
line 2
line 3
line 4
]]
-- local s - io.loaddata("yourfile.txt")
local lines = string.splitlines(s)
for i=1,#lines do
if lines[i] ~= "" then
context.foo(lines[i])
end
end
\stopluacode
\stoptext

Many of those are covered by typescripts. Those that are not, are on my machine because we needed them (often long ago) for a project (these are commercial fonts, in most cases typeone and of such a collection actually a few were used then). There are also some commercial fonts that I got for free. Then there are fonts that I have to check because users had an issue (public ones, of different quality and useability). Of those 'trying to cover all of unicode with different fonts of the same design' I tested subsets. And of course the fonts that come with the operating system (basically all fonts that context can access during a run). We're not going to make typescripts for every combination as in practice for most documents one needs a single setup and therefore only a handful of lines of code (and likely use some typescript file for a math font). There's also the selectfont mechanism that uses heuristics to do the same. There are plenty of examples in the distribution and for a specific style that demands certain fonts one can also put the definitions in the style.

My document decreased from 580+ pages to 500 pages after that. About your document, I assume you had a lot of Graphics because text only 180MB is too high. I have only few diagrams and my file size is only 3MB.
